From bd5df8520b5d1755c8c8a86a0f64d3aa452729ca Mon Sep 17 00:00:00 2001 From: Spencer Oliver Date: Tue, 5 Feb 2013 16:41:30 +0000 Subject: stm32: enable flash bank size override It has been seen on some stm32 targets that the flash size register that is probed by the driver may contain an invalid size. This change enables the user to override the probed value.
